12 Claims.

This invention relates to improvements in ranges, and more particularly to the type of range in which solid fuel is used, for example coal or wood.

Such ranges were made formerly with several doors on the front, used in adding fuel, adjusting the draft, removing ashes, or were otherwise useful in building up and maintaining the desired bed of burning fuel in the fire box. These doors, usually arranged one over the other in a vertical row, were provided in addition to the larger oven door and in some cases certain other doors as well.

The tendency at the present time is toward smooth, enameled surfaces for the outer walls of stoves and ranges and is away from the less pleasing appearance presented by a large number of projecting parts on the front of the structure such as are in evidence where the older type of door with side flanges, outside hinges and conspicuous handles are used, where the end of a shaker bar is prominent, and where the operating end of a draft regulator protrudes in a position near the fire door.

One object of the present invention is to provide a range of improved appearance in which the usual fire door, ash door and other parts are concealed by a single larger door or auxiliary door having a comparatively smooth exterior surface.

Another object of the invention is to provide a construction in which the draft door is mounted in the auxiliary door and in such a wayv that when said draft door is closed it does not protrude beyond the plane of such auxiliary door to such an extent as to be objectionable.

Another object is to provide two draft doors for the draft chamber adjacent the fire box, one of which doors is located in the front auxiliary door and the other of which is elsewhere located in av wall of the draft chamber, with means for adjusting both doors simultaneously.

A further object is to provide such draft doors with an operating handle accessible at the rear at the top of the stove or range, in an inconspicuous position.

An additional object is to provide a range having an ornamental, concealing door mounted at one side of the oven door and concealing the fire box doorjthe ash pan door and an intermediate and inner draft door which serves also as an ash shed.

Another object is to provide a range of this character in which the end of the shaker bar is concealed but is rendered accessible by opening the a door, which ope movement au= tomatically closes the combined inner draft door and ash shed to prevent the escape of ashes and dust while shaking the grate bar.

An additional object is to provide a range having an inside draft door in the front wall thereof 5 and an outside draft door in an auxiliary door, which latter normally conceals said front wall, said auxiliary door and said inside draft door having cooperating means whereby said inside door is always open when the outside or auxiliary 10 door is shut, and vice versa.

A further object is to provide concealed means for adjusting the opening of the outside draft door.

In the accompanying drawings in which a com- 15 mercial embodiment of the invention is illustrated:

Fig. 1 is a perspective view of the left hand side of a range with the auxiliary front door open;

Fig. 2 is' a rear elevation of the same side of 20 the range;

Fig. 3 is a top plan view of the same side of the' range with the upper part removed and the auxiliary door closed;

Fig. 4 is a similar view with the auxiliary door 25 open;

Fig. 5 is a sectional view on the line 55 of Fig. 2; and

Fig. 6 is a similar view with the auxiliary front door open.

The range is provided with a suitable base l0 supported on feet H and is provided with the usual top l2. As shown in Figs. 5 and 6, the fuel is supported on a suitable grate, including a rocking grate bar l3 which has a shaker bar It 5 accessible at the front of the range.

Where coal is the fuel it is introduced through the removable cover I5 and where wood is used as the fuel it is introduced through the inner fire door l6 which is hinged inside at the bottom at n, as shown in Fig. 6, whereby it may be swung downwardly by the handle l8. This door is always closed during operation.

Beneath this drop door 16 is a metal plate or closure l9 having an opening therein with a rearwardly extending horizontal shelf 20 at the bottom of said opening and an inner draft door 2!, hinged at the upper end 2 l closing said opening, and normally somewhat inclined, as shown in Fig.

6. This draft door tends by its weight to remain in closed position but has means for opening it as hereinafter described. When open, it projects farther inwardly, as shown in Fig. 5. By virtue of its inclination it acts as an ash shed to guide ashes into the ash pan, and when closed it serves also to prevent dust and ashes from escaping.

Beneath the closure plate I9 is another dust tight drop door 22 which is hinged at the bottom on the inside at 23 and may be pulled down by a handle 24 when it is desired to remove the ashes. At other times this door remains closed.

The upper and lower drop doors and the middle inner draft door just described and which are shown in front elevation in Fig. 1, are normally concealed from view by the auxiliary door or closure 25. This door, which is shown in open position in Fig. 1, is molmted on suitable hinges such as 26, near the bottom and a rotatably mounted pin 21 at the top. This door has an opening therein lined by a rectangular frame 28 on the inside within which the front draft door 29 is mounted. Said door is preferably hinged at the top at 39, having'a horizontal flange 30 at the bottom and connecting side flanges 30, as shown in Fig. 5. It also has a substantially vertical flange 3i at the top to provide an effective closure above the hinged support.

-The front door 25 has a rearwardiy projecting member 32, preferably of angle form, riveted to one of the vertical side members of the frame 28, as shown in Fig. 1. When the door is closed this inward projection engages the inner draft door 2! and holds the same open, as shown in Fig. 5. When the door 25 is open, said draft door closes of its own weight, being then in the position shown in Figs. 1, 3 and 6. The door 25 is provided with any suitable form of handle 33 on the outside,

which operates an inner locking bar 34, arranged to pass through the opening 35 in the cover plate l9 and engage the rear wall to hold the door shut.

In addition to the front draft door 29, there is also a second or rear draft door 36, shown in Figs. 2, 3 and 4. This door also is preferably hinged at the top as at 37 in Fig. 2. It may be conveniently 1 opened and held many desired position of adjustment by means of a vertical link 38 having notches or ratchet teeth 39 near the top thereof where the lini; passes through an opening in the top l2 of the range. The top of the link is bent over to form a handle 40 whereby the rear draft may be conveniently adjusted.

One of the features of the improved range is the auxiliary hinged door for concealing the various drop doors, previously described, and another feature is the simultaneous aiijustment of the front and rear draft doors to provide for an even flow of air upwardly through the grate. The

arrangement for simultaneously operating the draft doors in this instance shown in Figs. 5 and 6. The rear door 36 has a iink 4| pivoted to the 1 inside thereof and connected to another link 42 which is pivotally mounted on a support 43 carried on the end wall of the range. The upper end of the link 42 is connected to a further link 44, the front end of which slides in a strap 45. The link 44 has a bar of metal 46 riveted thereto with its forward end 41 curved and projecting through re-ctions when the handle 40 is moved up or down and thus both doors are opened and closed simultaneously, to any desired angle, provided the auxiliary front door 25 is closed, as is the case during the normal operation of the range, and, of course, the rear draft door 36 may be adjusted without reference to the front draft door 29, if desired, when the auxiliary front door 25 is open. It will be seen that the front door 25 can be opened while the two draft doors are in either open or closed position. The bar 46 is sufl'iciently flexible and is so mounted as to permit its curved, forward portion 4'5 to slide back and forth in the opening 48, in which it has a loose fit, without binding. The forward extremity of said bar engages the inner surface of the door 29 substantially at right angles thereto when said door is somewhat inclined as it is in closed position and it remains more or less at right angles to said surface as the door is opened, and, furthermore, it is prevented from siipp'ing or springing down too far by the transverse flange 30 at the bottom.

The auxiliary front door 25 is in effect an ornamental hinged cover plate extending from the top to the bottom of the range at one side of the oven door and in nearly the same plane therewith. By providing an opening in said cover plate, to give access to the end of the shaker bar, said door may be left shut when shaking the grate and under these conditions the fire door l6 and ash door 22 may be omitted and most of the advantages of the construction heretofore described, including the advantage of a smooth, enameled,

pleasing outer surface of the range, may be re-.

tained. With this simplified construction the ash deflector need not be hinged but fixed in position since the cover plate is closed when the ashes are shaken However, the preferred construction is one in which this shaker bar opening is omitted, making it necessary to open the hinged cover plate to gain access to the shaker bar and with this construction a tightly closed front such as provided by the fire door, the ash door and the intervening fixed plate with its hinged ash deiiector, is essential to prevent dust and ashes from escaping.

The arrangement of the auxiliary door or cover plate in combination with the other features described not only provides the necessary improved appearance but removes the draft handle from the front of the range where it was formerly located and provides a chiferent type of handle at the top of the range where it is easily operated without stooping. This draft handle also is selflatching. When there is a good fire in the stove this handle will be warm but is designed to be raised and lowered with a lid lifter. In order to close the draft, the lid lifter is used to push the draft handle a iittle to the right to disengage, whereupon the draft doors will drop of their own weight. Also, the new design allows the fire door to be opened without disturbing the draft assembly. With the old arrangement of draft handle front, it was impossible to open the fire door fuliy without being interfered with by said handle. The fact that both draft doors at the front and rear open simultaneously and are hinged at the top, insures a more even fire from front to rear, a better and'even bed of ashes, bet ter and more complete combustion, more even distribution of heat to the top of the stove and around the oven and permits of the use of a smaller and iower fuel bed, thus resulting in fuel economy an longer life of the range. v
